An operation unit 23 may be provided under the top plate 20. Theoperation unit 23 is operated to control heating power of the gas cooker1 by a user, and may be formed to be operated by the user's touchingoperation. The operation unit 23 may be configured with an electronicswitch or a sensor, or any other suitable a touching method.

An operation part 201 which enables the user to recognize an operatingportion of the operation unit 23 may be formed at an upper surface ofthe top plate 20 corresponding to the operation unit 23. The operationpart 201 may be formed at the upper surface of the top plate 20 in aprinting method or a film attaching method, and may also be formed in atransparent or translucent type so that at least a part of the operationunit 23 is exposed. Also, the operation part 201 may be formed not to berecognized from an outside through the top plate 20 before an operationthereof, but to be recognized from the outside by turning on a separatebacklight.

The operation unit 23 may be located at a front end of the top plate 20,and may be formed so that an upper end of the operation unit 23 iscompletely in close contact with the top plate 20. The operation unit 23may also be formed to be coupled to the top plate 20 and to bedisassembled from or assembled to the case 10 in a module state.

The opened upper surface of the case 10 may be formed to have a somewhatsmaller area than that of the top plate 20, and may also be formed tohave a structure in which the perimeter of the top plate 20 furtherprotrudes to an outside of the case 10 when being coupled to the topplate 20. An exterior of the case 10 may be formed by bending the steelplate material, and if necessary, may be formed by injection-molding aresin material.

When the top plate 20 and the case 10 are coupled to each other, a spaceis formed inside the case 10, and a burner unit 30 may be provided inthe space. The burner unit 30 may include a plurality of gas burners 40in which combustion of a supplied mixed gas occurs, and an insulatorcase 31 at which the gas burners 40 are fixed and installed.

Each of the gas burner 40 has a nozzle 33 for supplying the gas, and amixing tube 34 through which a fuel gas and air are mixed and introducedto a burner port 41 of the gas burner 40 may be provided at an outletside of the nozzle 33. The nozzle 33 and the mixing tube 34 may beformed in one module, and may be respectively fixed to and installed atthe burner port 41 of the gas burner 40.

The plurality of gas burners 40 may be provided, and may include a firstburner 401 and a second burner 402. Both of the first burner 401 and thesecond burner 402 may be seated on the insulator case 31 formed in asingle unit, and may have a structure which is installed inside the case10 together with the insulator case 31. The number of the gas burners 40and a size of each of the gas burners 40, which are installed at theinsulator case 31, are not limited to the proposed embodiment, and maybe variously applied.

A gas pipe 35 is provided inside the case 10. The gas pipe 35 connects aregulator 51 and a valve unit 52 with the gas burners 40 so that the gasis supplied to each of the gas burners 40.

The gas burner 40 may include the burner port 41 to which the mixed gasis supplied, a red-heat plate 42 which is seated at the burner port 41to be heated by the combustion of the mixed gas, and a burner holder 44and a burner cover 45 which supports the burner port 41 and the red-heatplate 42.

Specifically, the burner port 41 is formed in a cylindrical shape ofwhich an upper surface is opened, and the red-heat plate 42 is seated onthe upper surface. The mixing tube 34 which supplies the mixed gas isinserted and installed at one side of an outer portion of the burnerport 41.

The mixing tube 34 may be formed so that a plurality of tubes aredisposed at regular intervals to enable the gas supplied through thenozzle 33 to be evenly introduced into the burner port 41.

A plurality of nozzles 33 through which the mixed gas is injected has astructure which is fixed by a nozzle holder to be spaced apart from themixing tube 34, and an outlet port of each of the nozzles 33 is locatedat a location corresponding to an inlet port of the mixing tube 34.Therefore, the inlet port of the mixing tube 34 is located at thelocation corresponding to the outlet port of the nozzle 33 to be spacedapart by a predetermined gap, such that air is mixed together by apressure difference due to a flow of the gas when the gas is injectedthrough the nozzle 33.

The red-heat plate 42 is seated on an upper surface of the burner port41. The red-heat plate 42 is formed to completely shield the openedupper surface of the burner port 41. The red-heat plate 42 may be formedof a porous ceramic mat, and the mixed gas flowing on a surface of thered-heat plate 42 may be burned. The red-heat plate 42 may be formed ofanother material which is usable to the gas burner 40.

A spark plug 32 is fixed to and installed at one side of the burnerholder 44. The spark plug 32 serves to ignite the mixed gas in the gasburner 40, is provided above the red-heat plate 42, and extends from anoutside of the red-heat plate 42 toward an inside thereof to ignite themixed gas.

Also, a flame detecting means 321 may be provided at one side of thespark plug 32. The flame detecting means 321 serves to check an ignitionstate of the gas burner 40 through a change in a voltage or atemperature of the red-heat plate 42, and may be formed in a moduleintegrally formed with the spark plug 32, and may extend along with thespark plug 32 from an upper side of the red-heat plate 42 toward theinside of the red-heat plate 42.

A burned gas guide portion 444 formed to extend backward is formed atthe burner holder 44. The burned gas guide portion 444 may extend to arear end of the case 10 corresponding to a location of the grille vent21. Therefore, the burned gas generated when the combustion occurs atthe gas burner 40 may be guided to the grille vent 21 along the burnerholder 44, and then may be discharged to an outside.

The burner cover 45 is provided above the burned gas guide portion 444.The burner cover 45 forms a flow path of the burned gas flowing throughthe burned gas guide portion 444, and shields an opened upper side ofthe burned gas guide portion 444. A rear end of the burner cover 45 isformed to be spaced apart from a rear end of the burned gas guideportion 444, such that cooling air in the case 10 and the burned gaspassing through the burned gas guide portion 444 are mixed and thendischarged.

An insulator for preventing heat of the burner unit 30 from beingtransferred to the outside of the case 10 or some areas of the top plate20 may be provided between the burner holder 44 and the top plate 20 andbetween the burner holder 44 and the insulator case 31.

A main fan 61 and a sub-fan 62 may be provided inside the case 10. Eachof the main fan 61 and the sub-fan 62 is formed to have a box fan, andalso formed to suction air outside the case 10 and then to discharge thesuctioned air from an inside of the case 10. A structure of the fan maybe employed according to a user's selection.

The main fan 61 and the sub-fan 62 enable external air to be introducedto the inside of the case 10 having a sealed structure, andsimultaneously enable the air inside the case 10 to forcibly flow andthus to cool the inside of the case 10. The air forcibly flowing in thecase 10 may be discharged to an outside through the grille vent 21.

The main fan 61 may be provided at a space among the first burner 401,the second burner 402, a barrier 80 and the operation unit 23. That is,the main fan 61 is located at a location close to the operation unit 23,the first burner 401 and the second burner 402, and may cool theoperation unit 23, the first burner 401 and the second burner 402.

The air forcibly flows toward the operation unit 23 by driving of themain fan 61, and may cool a PCB 231 forming the operation unit 23. Alower surface of the top plate 20 at which the operation unit 23 islocated, in particular, the operation part 201 may also be cooled by themain fan 61. Therefore, through cooling of the PCB 231, the operationunit 23 and the operation part 201 of the top plate 20 may be cooled sothat the user does not feel discomfort due to heat generated whenoperating the operation part 201 of the top plate 20.

By the driving of the main fan 61, the air outside the case 10 isintroduced, and forcibly flows radially centering on the case 10, andsome of the air may flow along perimeters of the first burner 401 andthe second burner 402, and thus heat from the first burner 401 and thesecond burner 402 does not stay at the inside of the case 10, but isdischarged to the outside.

Therefore, a space of the internal space of the case 10 at which the gasburner 40 is provided may be cooled by the driving of the main fan 61,and may also protect electronic components in the case 10, i.e., the PCB231 and sensors forming the operation unit 23.

The sub-fan 62 serves to cool the valve unit 52 which is configured withan electronic valve such as a solenoid valve provided at one side in thecase 10, and may be provided at one side of an edge of a rear halfportion of the case 10. The sub-fan 62 is provided inside a spacepartitioned by a side barrier 63, and by the side barrier 63, a space inwhich the valve unit 52 is disposed may be partitioned from the space inwhich the gas burner 40 is provided.

Therefore, by driving of the sub-fan 62, the air outside the case 10 maybe introduced into the space partitioned by the side barrier 63, and thevalve unit 52 may be cooled separately from the space in which the gasburner 40 is disposed.

Specifically, the side barrier 63 may be fixed to and installed at abottom surface of the insulator case 31, and may be installed so thatboth ends are in contact with one of both of left and right sidesurfaces of the case 10 and a rear surface of the case 10.

The side barrier 63 may generally include a fan seating portion 631providing a surface on which the sub-fan 62 is seated, and an extendingportion 632 which partitions the internal space of the case 10.

Specifically, the fan seating portion 631 is formed in an approximatelytriangular plate shape, and also formed to be in contact with an uppersurface of a fan installing portion 11. The sub-fan 62 may be fixed tothe fan seating portion 631, and the side barrier 63 installed at theinsulator case 31 may be assembled inside the case 10 together with theinsulator case 31.

The fan seating portion 631 is formed in a right-angled triangularshape, and also formed so that one inclined end of the fan seatingportion 631 is connected to the extending portion 632, and the other endis in close contact with a side surface of the case 10. Therefore, theside barrier 63 may be maintained in a stably fixed state withoutvibration due to an air flow.

The extending portion 632 is formed to be vertically bent upward fromthe inclined end of the fan seating portion 631, and also formed to befixed to a lower end of the insulator case 31 and to partition theinternal space of the case 10.

The extending portion 632 extends along the inclined end of the fanseating portion 631, may further extend outward, and may include a firstextending portion 632 a which partitions the case 10, and a secondextending portion 632 b which is bent from an end of the first extendingportion 632 a and partitions a side exhaust port 315.

The first extending portion 632 a is formed to partition a space betweenthe insulator case 31 and the case 10, and to guide the flow of the airblown by the sub-fan 62.

The second extending portion 632 b is bent from the end of the firstextending portion 632 a, passes through the side exhaust port 315, andextends to be in contact with the rear end of the case 10. Accordingly,by the second extending portion 632 b, the side exhaust port 315 may bedivided into both of left and right sides based on the second extendingportion 632 b, and the cooling air flowing along the first extendingportion 632 a may be independently discharged through the side exhaustport 315 partitioned by the second extending portion 632 b.

A bent portion 633 which is bent outward may be further formed at anupper end of the first extending portion 632 a. The bent portion 633 isin contact with a lower surface of the insulator case 31. A fasteningmember such as a screw and a bolt may be fastened to the bent portion633 and the insulator case 31, and the side barrier 63 may be fixed andinstalled.

Each of the main fan 61 and the sub-fan 62 is installed to be in closecontact with an opening formed at the bottom surface of the case 10.Since the case 10 has a structure in which a remaining portion of thecase except a portion at which the main fan 61 and the sub-fan 62 areinstalled is sealed, the air introduced into the case 10 may beintroduced only through the main fan 61 and sub-fan 62.

The internal space of the case 10 may be partitioned by the barrier 80.The barrier 80 extends from a front end of the case 10 to the rear endof the case, and partitions the internal space of the case 10 into bothof left and right sides. The gas burner 40 is provided in one side spacepartitioned by the barrier 80, and an induction burner 70 is provided inthe other side space.

The induction burner 70 is provided at one side of a space partitionedby the barrier 80. The induction burner 70 may include an inductionheating part 71 which is installed at a lower side of the top plate 20and provides an alternate magnetic field to a cooking container put onthe top plate 20, and an induction case 72 which is disposed at a lowerside of the induction heating part 71 to support the induction heatingpart 71 and in which elements for operating the induction heating part71 are accommodated.

An inverter module 722 which supplies AC power to the induction heatingpart 71, and a switching element which is disposed as one of electronicelements of the inverter module 722 at one side of the inverter module722 and generates high temperature heat may be provided inside theinduction case 72. At this point, the switching element may be formed ina coupled state to a cooling means such as a heat sink. A control part721 for controlling an operation of the induction burner 70 may beprovided at one side of the induction case 72.

The induction case 72 is opened in forward and backward directions, andan induction fan 64 which cools an inside of the induction case 72 isprovided at an opened front of the induction case 72. Therefore, thecontrol part 721 and the inverter module 722 in the induction case 72may be cooled by driving of the induction fan 64. In addition, theinside of the case 10 may be cooled by discharging the air in theinternal space of the case 10, in which the induction burner 70 isprovided, to the outside.

The insulator case 31 and the induction case 72 which are provided atboth of left and right sides of the barrier 80 may be fixed to andinstalled at the barrier 80. To this end, coupling portions 723, 724,311 and 312 for coupling with the barrier 80 may be further formed atthe insulator case 31 and the induction case 72, respectively. Thecoupling portions 723, 724, 311 and 312 may be integrally formed withthe insulator case 31 and the induction case 72, and may be formed bycoupling a separate member.

A plate bracket 24, an extending portion 241 included in the platebracket 24, a top plate fixing portion 242, a bracket fixing portion243, an operation unit fixing portion 244 and a fixing portion 245 whichare not described will be described below in detail.

As illustrated in FIG. 5 and FIG. 6, the barrier 80 may include apartitioning portion 81 which extends from the front end of the case 10to the rear end thereof, a plate supporting portion 82 which is bentfrom an upper end of the partitioning portion 81 and supports the lowersurface of the top plate 20, and burner fixing portions 83 and 84 whichare bent from a lower end of the partitioning portion 81, coupled to theinsulator case 31 and the induction case 72 and fix the gas burner 40and the induction burner 70.

The partitioning portion 81 may be formed to be bent several times andto allow a smooth air flow without interference with the gas burner 40and the induction burner 70, and both of extending ends are in contactwith a front surface and a rear surface of the case 10, respectively.

The plate supporting portion 82 is formed to have a predetermined area,and may be formed to be bent outward from the upper end of thepartitioning portion 81. Therefore, the plate supporting portion 82 maybe bonded or attached to the lower surface of the top plate 20, and thusmay be fixed thereto. Accordingly, the barrier 80 may be fixed to andinstalled at the top plate 20.

The burner fixing portions 83 and 84 are formed to be bent outward fromthe lower end of the partitioning portion 81, and also formed to extendin a predetermined length. The screw holes 831 and 841 in which thefastening member is fastened may be formed at the burner fixing portions83 and 84. Therefore, the coupling portions 311, 312, 723 and 724 formedat the insulator case 31 and the induction case 72 are formed to befixed to the burner fixing portions 83 and 84 by the fastening member S,respectively. For example, the coupling portions 311, 312, 723 and 724of the insulator case 31 and the induction case 72 may be fixed to theburner fixing portions 83 and 84 by the fastening member S such as thescrew.

The numbers and locations of the coupling portions 311, 312, 723 and 724and the burner fixing portions 83 and 84 are not limited to thedescribed implementation, and if necessary, a plurality of burner fixingportions 83 and 84 may be formed at any locations of the barrier 80, andthe coupling portions 311, 312, 723 and 724 may be formed at locationscorresponding to the burner fixing portions 83 and 84, respectively.

The side surfaces of the insulator case 31 and the induction case 72close to the barrier 80 may be fixed by the barrier 80, and outer endsopposite thereto may be fixed by the plate bracket 24 provided at thetop plate 20.

As illustrated in FIG. 7 and FIG. 8, the top plate 20 is seated on thetop frame 22, and forms a surface on which food is seated, and thegrille vent 21 is provided at a rear of the top plate 20, and the platebracket 24 may be provided at the top plate 20. The plate bracket 24 isprovided at the lower surface of the top plate 20, and one pair of platebrackets 24 may be provided at both of left and right sides facing eachother. When the top frame 22 on which the top plate 20 is seated isseated on the case 10, the plate bracket 24 is located inside the case10.

Specifically, the plate bracket 24 may include the extending portion 241which extends along the lower surface of the top plate 20, the top platefixing portion 242 which is formed at an upper end of the extendingportion 241 to be fixed to the top plate 20, and the operation unitfixing portion 244 which is bent inward from a front end of theextending portion 241 to fix both ends of the operation unit 23 providedinside the case 10.

The extending portion 241 extends along each of both side ends of thetop plate 20 in forward and backward directions, and the top platefixing portion 242 is formed to extend inward from a rear end of theextending portion 241. The top plate fixing portion 242 is formed tohave a predetermined area, and provides a stable coupling force to thetop plate 20. That is, an upper end of the plate bracket 24 includingthe top plate fixing portion 242 may be bonded or attached to the lowersurface of the top plate 20, and thus may be fixed thereto.

The bracket fixing portion 243 which is bent downward is formed at thetop plate fixing portion 242. Each of both of the bracket fixingportions 243 and 246 is formed to extend to one side of each of theinsulator case 31 and the induction case 72, and may be fixed by thefastening member such as the screw passing through and fastened to theinsulator case 31 and the induction case 72. Therefore, the insulatorcase 31 and the induction case 72 have a structure which is fixed to theplate bracket 24.

Due to such a structure, both ends of the gas burner 40 and theinduction burner 70 may be fixed to the barrier 80 and the plate bracket24, respectively. Since the barrier 80 and the plate bracket 24 areattached to the top plate 20, the gas burner 40 and the induction burner70 may be attached to the top plate 20 in a module type.

The operation unit fixing portion 244 may be extend inward from an endof the extending portion 241, and may be fixed to each of both of sidesurfaces of the operation unit 23. Accordingly, the operation unit 23may also be coupled to the top plate 20 in a module state. The fixingportion 245 which extends perpendicularly to the operation unit fixingportion 244 and is in contact with the operation unit 23 to furtherstably fix the operation unit 23 may be further formed at an end of theoperation unit fixing portion 244.

As illustrated in FIG. 9, when a user operates the operation unit 23,and inputs an operation of the gas burner 40, opening and closing of thevalve unit 52 is determined according to an operating signal, and thusthe gas may be supplied to the desired gas burner 40.

When the gas is mixed with the air, and then the mixed gas is suppliedto the gas burner 40, the mixed gas is ignited by the spark plug 32, andthe combustion occurs at the red-heat plate 42, and thus the red-heatplate 42 may be heated. By heating of the red-heat plate 42, a radiantwave may be emitted from the red-heat plate 42 to an outside, and thusmay heat food or a container including the food which is seated on thetop plate 20.

The user may control heating power of the gas burner 40 through anoperation of the operation part 201, and may also visually check anignition state of the gas burner 40 and a heating state through the topplate 20 because visible rays are included in the radiant wave.

The main fan 61 and the sub-fan 62 are driven along with the ignition ofthe gas burner 40. By the driving of the main fan 61, the air in thecase 10 may be suctioned toward the main fan 61. The suctioned air isdischarged radially centering on the main fan 61.

Some of the air blown through the main fan 61 flows toward the PCB 231of the operation unit 23, and thus the PCB 231 is continuously cooled tobe normally operated, and also a front half portion of the top plate 20,particularly, the operation part 201 may be cooled.

Some of the air blown through the main fan 61 may pass between the firstburner 401 and the second burner 402, may flow to a rear side, and thenmay be discharged through the grille vent 21.

As described above, by rotation of the main fan 61, the air in the case10 continuously cools the front half portion of the top plate 20 atwhich the operation unit 23 is located, and the air close to the firstburner 401 and the second burner 402 is discharged, and thus an internaltemperature of the case 10 is prevented from being increased to a presettemperature or more.

When the sub-fan 62 is driven, the air outside the case 10 may beintroduced into the case 10, and may independently cool the internalspace of the case 10 partitioned by the side barrier 63. That is, due tothe driving of the sub-fan 62, the valve unit 52 may be cooledindependently.

The heat generated upon the combustion of the gas burner 40 may beeffectively cooled by the main fan 61, and then may be dischargedthrough the grille vent 21. Also, the heat may be prevented from beingintroduced toward the induction burner 70 partitioned by the barrier 80.

As illustrated in the FIG. 10, when the user operates the operation unit23, and inputs an operation of the induction burner 70, the control part721 and the inverter module 722 are driven according to an operatingsignal, and the alternate magnetic field is formed at the inductionheating part 71, and the container including the food which is seated onthe top plate 20 may be induction-heated.

Meanwhile, at the same time when the induction burner 70 is operated,the induction fan 64 is operated, and the induction fan 64 blows thecooling air from a front of the induction case 72 toward a rear of theinduction case 72.

The air blown toward the rear effectively cools the inverter module 722generating heat, while passing through the induction case 72, and alsocools other elements including the control part 721. In addition, someof the air blown by the induction fan 64 discharges the air in theinternal space of the case 10, in which the induction burner 70 isaccommodated, to the outside through the grille vent 21.

As described above, when the gas burner 40 and the induction burner 70which are provided at both of the spaces partitioned by the barrier 80are operated, cooling structures may be formed independently, and thecooling air in each of the spaces may not be introduced into theadjacent space by the barrier 80, but may be discharged, and thus thestable operation of the induction burner 70 may be ensured.

In some implementations, the combination type cooker may not beinstalled at the furniture such as the sink in a built-in method, butmay be independently installed at a separate case.

As illustrated in FIG. 11, a combination type cooker 1 may be formed tobe seated on an outer case 10′ which forms an exterior while the topplate 20 and the case 10 are assembled.

In some implementations, the top plate 20 may be directly installed atthe outer case 10′, and all of the elements including the burner unit 30which are disposed in the case 10 may be installed inside the outer case10′.

Although implementations have been described with reference to a numberof illustrative implementations, it should be understood that numerousother modifications and embodiments can be devised by those skilled inthe art that will fall within the spirit and scope of the principles ofthis disclosure. More particularly, various variations and modificationsare possible in the component parts and/or arrangements of the subjectcombination arrangement within the scope of the disclosure, the drawingsand the appended claims. In addition to variations and modifications inthe component parts and/or arrangements, alternative uses will also beapparent to those skilled in the art.
